Peachtree GaN 1 Beta

Is it safe to bypass the first fuse in the IEC outlet? How do I tell if it's fast or slow for the ceramic one inside? 

OK, please do a serious evaluation and let us know......thanks.

BTW....how does the Rose do digital out volume control? At 32Bits? or ? What digital cable are you using?

Here is the feedback from the Rose engineers...

Basically, for OPT OUT/ AES/EBU, and COAX OUT, the maximum possible transmission rate is 24Bit/192KHz.
If you use internal DAC of Rose, you can use full specification of Rose streamers, 32bit 768kHz for RS150B.
Lowering the volume won’t degrade bits.

I make all my own cables, take a look at my system details.  

Is the Gan 1 the only class D amp that uses zero negative feedback or the only one that simplifies the chain, eliminating the need for all these separate components?

@ricevs I’ve gotten caught up in this now…I remember canceling my order to trial this for $1499 because I couldn’t get a definitive date for delivery back in April…oh well.

Since I’m a futurist and like most audiophiles am interested in the next best thing, what comes after GanFET or is that it? I asked over on the AHB2 thread but probably more appropriate to keep it here.

It's not class d, it's a digital amp. Technics has a ganfet digital amp also. 

A digital amp is a class D amp......but it has digital input and not an analog input. It changes the PCM directly to PWM in software and then drives a class D output stage. It does not use digits to drive the speaker. What comes out of it is analog. You might say a "digital amp" is a "power DAC". A digital amp is not a normal "class" of amp. It is just the name that TACT and Lyndorf and Technics use to describe their amps. Peachtree does not call it anything but an "amp".

Lyngdorf and Technics also make "digital" amps (Tact, now out of business, morphed into Lyngdorf). The Technics and Lyngdorf both have analog inputs along with digital inputs but the analog signal is changed to PCM with an ADC before going to the main chip to be changed to PWM. The Peacetree is the only "super simple" digital input class D amp made.....super simple meaning just a digital input and no volume control. The amp module inside the amp is inexpensive and you will see others using this technology......and other more high end complanies developing their own PCM to PWM conversion software and building their own digital amps. They will naturally be used in powered speakers, as well.....so you would have all the xovers, equalizaion, time alignment done inside speaker in the digital domain and then fed directly to the speaker drivers.....this will be fantastic!  However, then there will be less to tweak....Hey, where is the fun in that? Just fantastic sound? boring....he he.

If you buy the Peachtree and love it.....you are no longer looking for analog interconnects, DACs, or Preamps.....you simple do not need these components......Using the money you save, you can get a serious inverter like the Giandel 5000 watter and the Puritan line filter after it and blow your mind to kingdom come.

Here ya go Ric....put a couple pics in my profile

This thing sounds so good. I remember the old days and stacking multiple components to achieve the perceived best audio performance.

I feel bad because I love building all my cabling and this trend reduces it down to PCB traces.

Very simplistic interior. Cheap CMC binding posts, basic IEC inlet, RCA wiring.

I’ll modify all this stuff. My ears are old, so not convinced it will make any difference...

Just to note. I have the Peachtree GaN400 and I think I like the GaN1 better.

Thanks for the pics......now I see even more I can mod.  So far, everyone who has tried this thing has loved it and it beat whatever they had before.  I wonder how good it could sound with a Lumn U1 mini ($2400) with its super lossless LEEDH volume control?  What DAC, Preamp, amp combo can beat this thing?  So far, nothing.

What really caught me was how dead silent this thing is.   I'm primarily listening to audio from my OLED TV and it is tremendous (thru my Rose 150). Voicing is amazing and watching sports (ESPN) is impressive.

Don't know how much the Rose helps (just passing a digital coax), but hate by-passing their ESS DAC.  

I don't know about front ending this thing with something other than a cheaper Node or iFi.  Sweet spot seems to be a great second room system.   

I would think the lumin would make a big difference. I believe it reclocks the signal as well. I was looking at upgrading to the lumin as well. 

mbolek,

On one had you rave about the sound.....and then with the other hand you say its best use is using it with cheap streamers in a secondary system......HUH? How can you be raving about the sound in your main system and say this?

I think that this thing has incredible possibilities.....in even the MOST high end system...yes, indeed. Do you know how much difference ethernet cables make? Ethernet switches? digital cables? footers? modding? streamers? digital volume control? running your entire system on an inverter with the Puritan AC filter afterwords? The people who are loving this thing have barely scratched the surface of what this thing can do. As you see, I am excited about this thing. When I first heard about the TACT integraded digital amp in the late 90s I thought that it was over for "regular" audio. Well, the TACT had its problems......and now it is 25 years later. The Peachtree, so far, has no problems.....and so far, it is beating $15K worth of great separates. What else will it beat?.....and like I said.....wait till people tweak more and really find out what this thing can do.

Here is a link to a review of a bunch of digital cables (all with bnc connectors). The same difference would still be there if using rca connectors. This will give you an idea of the differences EVERYTHING makes. We have only just begun!

I didn't really understand what he's saying either. I'm betting his hifi rose sounds much better than the node, it does more than just pass a signal. I got some big improvements with ethernet switches and adding a lps to my node. I look forward to hearing about any mods you do. I'm looking at adding purple fuses right now. 

You want more? How about making your own speaker and bi-amping with two of these amps. You get a miniDSP Flex (digital out version) $500 and you use this as your digital xover after your streamer......it has two digital coax outs so you can use one amp for each channel. You set the xover wherever you like and at whatever frequency you want (all done at 32 bit/96K). You make an open baffle, partially open baffle, or box speaker using super pure woofer and tweeter......I would use a 10 inch cone woofer (or maybe two Purify 7 inch woofers in parallel) and cross it/them over to a super AMT or Beryllium tweeter in a wave guide around 1.3 K. You hardwire your speaker wires directly inside the amp and directly to the voice coil wires on the woofer and to the tabs on the tweeter......This will kill most $100K systems.....no doubt. Of course, you can get another digital xover and more amps and do 3 and 4 way speakers, as well. You can equalize for flat at your listening position...time align, etc. all in the digital domain.....again...no DACS, no preamps, no normal amps, no analog interconnects and no transparency robbing and dynamics robbing passive xover parts......OMG.....mind blowing possibilities.

What is so cool is that anyone (above the age of 10 with normal IQ) can do this. You do not need to know most of the parmeters of the drivers and how to design a perfect passive xover. You just play in the software and then measure using a measurement mic and your ears. Of course, the Q of the drivers and the size of the box (if using one) has to be taken into consideration for bass loading. Pretty simple really.

I received my GaN1 + Node 2 weeks ago and have been listening to it everyday for a few hours.  While waiting (& waiting) for the combo to arrive, I went ahead and ordered the Teddy Pardo lps for the node and had it waiting (& waiting) for when the rest arrived.  Didn’t even bother testing the node without the lps lol.  
I'm replacing a Rega Elex R + NAD C658 combo and have Triangle Borea BR08’s with a REL t9/x using speakon.  I’ll mention that I’d like be keeping the C658 if it had digital coax out.  
The elex-r/c658 was a funky combo due to the rega being an ia and the nad being a preamp.  Needless to say, it loved them with the BR08’s.  The BR08’s (I’ve read) can be a touch bright if not paired carefully and the Rega was a great amp for them.  Very natural and polite.  Convincing soundstage and nice dynamics across the fr.  Not the last word in detail, but a very nice setup (especially for the deals I found on the nad and triangles).  My biggest complaint was that everything didn’t really “wake up” until around 25% volume, which is too loud for evening listening.  The speakers are 92db sensitive, so the 72w of rega class a/b should have been plenty for quiet sessions.  Just left me wanting more though.  
Figured I could do with some more headroom right around the time PT announced the beta.  200wpc, DAC-less, zero feedback, cutting edge design used in much more expensive amps?  Sign me up.  
2 weeks in and I couldn’t be happier.  I was worried the GaN would come off bright on the BR08’s, but it isn’t an issue at all.  Not a hint of harshness to be found.  I’ve got some tinnitus, so I can be touchy with some hf and can get fatigued pretty quick in the wrong conditions.  Extended sessions with the GaN have been nothing but pleasant.  I haven’t done a quick-swap a/b test with the rega+nad combo, but I had the rega for around 5 yrs and the nad with it for the last 1.5yrs, so I’m pretty familiar with what I was used to hearing.  Comparing it to the GaN1, I can’t find a single parameter where I preferred the rega+nad.  Soundstage?  It was good before, but now it’s great!  The separation between instruments, the air/space around instruments/effects is profoundly better.  Previous setup had good depth, but the PT is deeper while also being more forward and throwing sounds behind/around my listening position.  My music lounge is untreated aside from carpet and soft furniture (room treatments are next up), so I know this will only get more precise once the room is dialed in better.  The triangle’s cellulose paper midrange driver already was very natural and a true highlight of the speaker, but paired with the GaN1, vocals (m & f) have more texture and presence.  Percussion sounds like it’s in the room with you.  If I were a drummer, I could prob tell what make/model drums, heads and cymbals are being played by how real they sound.  Strings sound superb, all of it.  I’ve thrown the kitchen sink at this amp and it hits a home run with everything.  
I understand the node is the weakest link and I’ve been thinking about adding the ifi ipurifier 2.  What’s kept me from pulling the trigger is the male coax output on the ifi.  Do I just plug it straight into the amp and have all the stress from its weight and cables be supported by a single rca?  I feel like that could cause some issues down the line?  I’m running a kimber ascent series coax and it’s very stiff and I feel like it would be unforgiving.  Does anyone have experience with using a node as a transport with the lps upgrade and a ipurifier2?  Does this push the node into proper streamer (lumin) territory?  
Anyways, I’m completely sold on the GaN1 and very much look forward to upgrading my triangles at some point.  I’d love to hear some Q Acoustic Concept 700’s on this amp.  I’d also love to hear this amp with a few of the previously mentioned internal upgrades and would be curious to know the cost of having work like that done?  I swapped out the ps on the node, but that was super-simple/low-risk.  
Looking forward to hearing more feedback once these amps get out in the wild more and others begin to see the light!

 

On one had you rave about the sound.....and then with the other hand you say its best use is using it with cheap streamers in a secondary system......HUH? How can you be raving about the sound in your main system and say this?

My statement should have been that most people would not spend the money on the 150 and just use the digital out to the GaN1.  Agree using the best possible streamer will enhance the GaN1 performance.

Ric - I love your idea with using the Flex and may have to look at using (2) GaN1s for an active system with my Camerton's and Purifi woofers.   Interesting....

Here is a link to a review of a bunch of digital cables (all with bnc connectors). The same difference would still be there if using rca connectors. This will give you an idea of the differences EVERYTHING makes. We have only just begun!

Curious that you don't feel that BNC connectors/connections make a difference.  Aren't they supposed to be superior to RCA since they are truly 75ohm terminations.

I did not say that bnc connectors were inferior or superior to rca. You would have to listen to the connectors to know which is better. What is on the GaN 1 is an rca. If you add an adapter, then you add the "sound" of an adapter. If someone really has to have a BNC connector then I could add one to the GaN 1 as part of a mod. Personally, I would not do that.....just use a better rca connector and better wire going to the board....but who knows?

The 75 ohm thing is really only one small factor in the sound of things. Years ago I bought this "pure 75 ohm" digital cable from Goldmund....that was suppose to be baked in an oven to insure perfect 75ohm......well, I made my own digital cable in a few minutes using high purity six nines copper twisted together and just regular rca’s.....and it slaughtered the Goldmund cable for sound purity. My cable was who knows what impedance. There are sooooooooooooooooo many things that make a sonic difference. Getting hung up on 75 ohm or whatever single thing will not get you great sound.

Ok.  So for anyone that cares, here are my mods to the GaN1.

1.  Replaced power inlet/fuse with a pure copper (Viborg) IEC.

2.  Replaced internal power wiring with VenHaus 12awg wire.

3.  Added KLE copper binding posts

4.  Triple C (Audio Revere) speaker jumpers to the GaN1 modules.

Pics added to my profile.  Love doing these mods. never really know if they make any difference.  I always tell myself that it sounds better....

Thinking that I'll bypass the RCA plug and run a direct connection to the PCB.  The internal wire is standard OEM.

Know the power and binding post connections feels more secure, I love using pure copper.  Never worried about the oxidation as I have seen more tarnishing with silver coated terminals.

@ricevs  take note to the twists on the speaker jumpers, opposite turns for positive/negative, does everything matter.....just kidding

Yeah,  I'm not going to add RCA/BNC adapters to the mix.  We'll never find a streamer that has a BNC digital coax connector.  I remember the old days using BNC, just liked the secure connection.

As I mentioned in the previous post, may run the coax straight to the board.  

After listening for the last hour, something is better.  I'm thinking the speaker jumpers may be the improvement.  I never liked the ferrite beads (what was on the stock speaker wires).  I really don't buy into the power side, other than a more secure/tight connection.

I see you love to tinker.  Each of the different things you did should be audible. "never really know if they make any difference" seems very odd to me.  Everything I do in my system I hear and can describe.  Wire will sound best twisted in the same direction.....not opposite per phase.  Usually sounds best if you twist the wire in the direction of its internal windings.  Most wires it would be clockwise.

The important thing is to have fun.  Looks like you are enjoying yourself.....good for you.

Does anyone else have a rel hooked up to their G1 with speakon?  Mine gets a double “kick” whenever the amp sleeps/wakes.  Anyone else happen to get this?  I’m an always on kinda amp owner, so I wish there was a way to disable the sleep mode…

Also, regarding the node’s digital volume: does anyone know what it’s lowest volume level is before it starts sacrificing bit depth?  Is 50% or higher volume the only levels that are bit-perfect/lossless?

Has anyone compared this amp with the recently released Atma-Sphere Class-D one? Since this one applies no loop feedback, while the Atma-Sphere does apply loop feed-back, I'd be interested in knowing how they compare, especially with music with a lot of transients.

@atulmajithia Its not a simple as you are asking- your question suggests to me that the amps you've heard that use feedback didn't use enough (which describes most amps made). Imagine a bell curve with the bell being the amount of harm caused by feedback, with zero feedback on the left and really a lot of feedback (+35dB) on the right. The reason it happens this way has to do with non-linearities present where the feedback is returned to the input of the amplifier, causing the feedback signal to be distorted before it can do its job, so distortion is created while innate distortions are suppressed (for the most part). If you can add enough feedback though (+35dB or more at all audio frequencies) then you overcome this problem.

When you get over that hump, then the feedback isn't doing the damage it does when its somewhere in the middle. Strictly in our own comparisons to our zero feedback triode class A OTLs, our class D sounds remarkably similar.

This amp is not really about zero feedback.....it it MUUUUCH more. This amp is revolutionary. You are eliminating the DAC, Preamp, regular amp and analog cables. LESS IS MORE. I am pretty sure the stock GaN 1 is not quite as good as $400,000 worth of "normal" state of the art components. But a super tweaked version of this technology would, I am sure, beat the $400K electronics.

How much do you have to spend to beat this thing?.....$40K....more? So far, the stock unit has beaten $15K worth of super gear with it being sourced by a $400 streamer with a linear power supply.

If you are heavily into vinyl then I can see it would be hard to move in this direction as you have to run your phono stage through an ADC to convert it to high speed digital. But, if you listen to digital only and you have a system budget of $30K or less than I think there is NOW only one choice for most pure sound.....the GaN 1......If you like tube sound and have to have super liquid sound then again this is not your cup of tea......but solid state these days is pretty darn good.....and this thing is probably the king in the $20K solid state electronics game......and it costs $2K!!!!!!!! This will allow you to buy a better streamer with better digital volume control, super ethernet switching, super coax cable and better speakers and speaker wires...... for WAY, way better sound than what you currently have. This is just so cool. All the "normal" class D amp manufacturers, including Atmasphere, Merrill, AGD, Orchard, Purifi, Hypex, IcePower, etc. are now put on notice.......YOUR STUFF IS OBSOLETE! he he

You will see some of these manufacturers soon playing with this technology and other companies not currently making class D will join in the game. You will see $100,000 digital amps from Boulder and Gryphon.....you will see $25K digital amps from Classe, Luxman, Levinson, etc.....you will see $10K digital amps from lots of people and you see RIGHT NOW.....the Peachtree GaN 1 at $2K

Dealers do not want to know about this product.....this will kill the sales of their $3K-$20K integrated amps, and separates. This is a radical new thing that is going to shake up the "normal" audiophile community. Naturally, your 1 percenters will still want the mega buck linear amp systems. BUT YOU want this....if you value sound quality. And you can have it right now.

This is just the tip of the iceberg....bi and triamping your speakers using zero analog xover, powered speakers with everything built in.....it is all coming....very soon......everything controlled perfectly in the digital domain....time aligning, perfect bass in your room......THE FUTURE IS NOW!

Interesting would love to hear one. I wonder if they demo models they send out for evaluation? I personally would do that if I was a Hifi manufacturer/seller. Would be a pretty easy sell right? Beat the s..t outta my 20k tube mono blocks. Of course I’ll take 2 .. 

They have a 30 day return window. 

They are sold with a 30 day money back thang.....so anyone can try one.....including any dealer. But then you would have to sign up as a dealer to sell them. And why would you want to sell them when you hardly make any money on it. You want to sell your $6K tube amp or whatever, plus DAC plus preamp plus cables. And it is not an easy sell as audiophiles are mostly loners and already have an opinion about things. This thing is off the charts weird. If it is so good (and it is) then how come a zillion poeple aren’t buying it? Because they just bought a new DAC or cable or preamp or amp....and now you all going to tell them that all that stuff is obsolete? They don’t want to believe it. They have too much ego and money invested in what they "think" is right. Also, you need a streamer or software with a good digital volume control (some of the expensive server/streamers do not have volume control because they are selling to a market that uses DACs and preamps). If you think about it....even Peachtree is probably not crazy about this thing. Since it beats their (now discounted) $3.5K separates......then they make less money. They need to make a dual mono version using the 400 watt boards and bigger power supplies and also have I2S and Usb inputs....and make it bigger and sexier....then they could make more money. I hope Peachtree is following this thread.

However, there are a few players out there that are now purchasing this thing and they will keep chiming in here and then you will see Darko review it with the Blue Sound and he will rave and that will help some but it will take a long time for most conservative audiophiles to embrace such a novel and cheap thing.....they will scream "this thing weighs 11lbs.!!!! it cannot be good.....it cost nothing....it cannot be good". I am doing my best to tell the world about this thing. I believe in it. I know it works......it will make many, many people happy. I like happy people. Goosebumps for the masses!!!!!

Kinda drunk so will just ask again instead of reading through posts. 
 

What are you personally coming from that the Peachtree betters? And what speakers? 

Musical fidelity m6s prx, denafrips ares ii. Transpuls 1500 

LSA and Peachtree have been using the same GaN fet class d modules. No feedback and a very load dependent frequency response, just like the old Tripath class d amps from 25 years ago. Out of date design with the flavor of the month fet. Ask Peachtree for some frequency vs load data and compare to modern class d designs like Hypex, Purifi, etc., which are ruler flat...Pig with lipstick.

You must be fun at parties.... It’s a different module. Maybe just listen to it instead. Who cares about load data and rulers? It sounds amazing. Stay ignorant my friend

Early in the year when this came up I tried to sign up as beta tester but unfortunately Peachtree wanted to limit to testers in the US, which I'm not. So I'm an interested follower in this thread.

@ricevs is overwhelmingly enthusiastic about this, and he's going in the direction I wanted to experiment. I have an active 4-way system with DIY speakers, software-based digital crossover, time-aligned, etc. My midbasses have been driven by Hypex UcD400 for some years and it's time for a change so I've been looking into the new GaN amps in the cheaper range and the GaN1 beta trial came up. From reading user comments from LSA and Peachtree GaN400 and Atma-Sphere's I've been wondering if they might replace my tubed McIntosh MC275 in the midrange also. This could lead to placing a GaN1 inside each speaker and drive midrange and midbass with separate channels (plus a cleaner look with the amps inside the speaker). Top end for now would be left to my Yamamoto 45-type SET driving AMT tweeters, but maybe the rest could be turned to GaN1.

@ricevs when you envision a system with digital xo and digital cables going straight to the multiple GaN1 in an active setup, which piece of equipment are you thinking about to distribute digital signals? Something like a Focusrite RedNet handling digital-in thru ethernet and digital out to GaN1s?

Today I have a Lynx Hilo that receives 8 digital channels thru USB, outputs 6 analog and 2 digital into a MiniDSP 2x4HD that handles the subs optimized with MSO. I had been thinking of replacing the Hilo with a Merging Hapi for multiple DAC channels, but this discussion is making me revisit and maybe I'll need something different if I went down this path.

Will be looking forward to more comments from beta testers. Keep them coming please!

@chrisld - Next I used the iFi Zen Stream (running from linear PSU) direct to the GaN1 and the Stream-iFi app to control the volume. The sound is stunning. It is so transparent, dynamic and enjoyable that it beats my much more expensive system. My class AB amps have a higher power rating, but you would never know it from the way the GaN1 sounds. The control is that good. I wonder what the damping factor is.\

I wonder myself too but, since the Gan1 menu is not even out, there seems no way to find out for the time being.  I guess its DF won't be high especially at the low freq. because of the "zero" neg. feedback.  In general, low neg. feedback -> low output impedance -> low DF.  The Gan400 has low neg. feedback and its DF at 1k hz is reported as merely 230ish.  This is usually translated to low DF at low end freq.  But the number does not matter if "the control is that good."  I am tempted.

I have seen the critique for Tact Millennium saying the top end sounds a bit too much energy, agreesive not too natural.  That gets me thinking about the bright sometime edgy sound characteristic of the traditional Class D amp (or digital amp whatever you call it).  Is it the case here?  I guess not due to the merging modern Class D technology made twenty years later.  Could you confirm? 

You must be fun at parties.... It’s a different module. Maybe just listen to it instead. Who cares about load data and rulers? It sounds amazing. Stay ignorant my friend

@donnylovely

Different module, still no feedback. Perhaps if you knew why load dependent frequency response is relevant you wouldn’t be making such ignorant and rude comments. Here’s why: when amps have load dependent frequency response, they don’t sound the same with varying loads. What that means is they can sound different not only across the frequency spectrum with one’s speakers, but can sound different when used with different speakers. There is thus no guarantee that they will sound "amazing" with any or every speaker, disregarding the differences in tastes amongst listeners. Therefore, one can take the impressions of listeners here with less than the usual grain of salt.

Just emailed Peachtree and signed up for the Beta test program for the GaN 1.  My current system is as lifelike as any I've heard recently except the $40K system Matterhorn was showing at the Tampa Florida Hi Fi Expo a few months back.  I'm a Big believer not just in individual products.(..Honestly, just about Every product in Hi Fi audio is good) but in system synergy.....mixing components to realize that elusive Magic Sound we are all looking for. Currently I found that Magic with the Audio-gd Vacuum HE-1 SE with 10 tubes and it's own regenerative power supply...the Peachtree Gan 400 amp....Audio Mirror Toubador IV Dac...CEC CD transport ( belt drive) and Klipsch Heresy IV's.......but interested to try the GaN 1. Is it still $1499 on the Beta test....

Isn't that every amp though? Is there any amp that is great with every single speaker? The point seems kinda moot

@donnylovely 

No, that isn't the case with every amp, only poorly designed ones. Most well designed amps don't change character with load.

@mbmi the beta test is over, it’s 2k on the site.

@ricevs do you have one of these amps? What system has it replaced for you?

@kuribo you’re missing out on a great amp because of your prejudices. Have fun listening to those measurements. Plus if you haven't heard or used it, your opinion on how it preforms aren't valid at all. 

@donnylovely 

Sorry, I have no interest in poorly designed products nor can I talk myself into enjoying their flaws. Get yourself a Sonos class d amp and save yourself $1500. Everyone says it sounds amazing so it must be spectacular!

Re Kuribo comments:....We have 7 people commenting here that this thing sounds amazing on THEIR speakers. We have ZERO people saying it does not sound great on THEIR speakers. When the number of praises gets to 100 will you still come on here and say the same thing over and over again? Please listen to the amp and see if it sounds good on YOUR speaker.....the only thing that matters. However, we all know that you will NEVER listen to this amp so anything you say here is meaningless to anyone but you and other (measurements are everything) people. So, why waste your and our time? Are you a kill joy? You can live in praise and gratitude and be happy or live in put downs and righteousness and be unhappy. It is up to you. You choose every moment. We all do.

I have not researched all the possible digital xover options out there. I suggested the Minidsp flex for a two way because it is inexpensive and works at 32bit and 96K and would be easy to implement using two GaN 1’s.

I do not have a GaN 1 here yet........please send me one......I will make it sound much better.

So far, no one has said this amp is bright, grainy, two dimensional, unmusical or anything like that.....If it beats a Holo May KTE DAC with Holo Serene Preamp and Kinki B7 monos........it must be pretty darn good. Only YOU can know what it will sound like in your stereo......30 day money back....nothing to lose.

@kuribo then why are you even commenting on this thread then if you belive that to be true about this product? The fact that you’re posting on here suggests you do have an interest. Plus the fact that you’ve never tested this item means you have no way to know if it is built good, bad, or otherwise. Keep you comments to yourself unless you actually know what you’re talking about. You're just making a ton of assumptions and being annoying to the people that actually have interest in this product. 

@donnylovely 

I think I have as much right to post here as you do so if you don't like my take, ignore it.

@ricevs 

More hype for your mods eh? The shilling never ceases.

We have 7 people commenting here that this thing sounds amazing on THEIR speakers.
 

OF COURSE it does! And there are 672 reviews on Amazon of the Sonos amp that say IT'S AMAZING! And it's ONLY $699! And you DON'T NEED a DAC! It's a TOTAL GAME CHANGER! 672 RAVE REVIEWS! It's revolutionary!

@kuribo of course you have the right. But you're just making yourself look dumb talking all this nonsense when you have no idea what you are talking about. There's no way you could know without actually having the product. All these measurements of other products are useless when talking about this product. If you actually listen to the GaN 1 and test it out , then please share your thoughts on it. You seem to need to be the smartest guy in the room, but you just guessing and assuming everything does not make you that. It isn't useful to anyone except your ego. 

@donnylovely 

Those who think that comments about this amp's sound characteristics are applicable in their own systems are being fed a bunch of nonsense. I don't need to hear it to know that load dependent frequency response is undesirable in an amplifier. That isn't guessing and assuming, it's a fact.

Yikes it is back the Pokémon. 

@kuribo So you know for a fact this has a bad load dependent frequency response and that peachtree did nothing in the design of the amp to compensate for it? 

@donnylovely 

That's what I am hearing. It has zero feedback which has been synonymous with load dependent frequency response in class d amps historically.

That would be called an assumption. If you actually listen to the amp with two different pairs of speakers of different resistances and the sound falls apart then it would be fact. What has been true in the past doesn’t necessarily mean that it’s true with this amp. Even if it is true with this amp, they might have found a way to compensate for it. But then again it could be totally true. At least actually find out though before touting opinions as facts and telling everybody it is crap. @kuribo
